docs: update auth signed retry examples

[DhruvPareek]

Summary

• Update signed-retry examples to show Request:<uuid> request IDs.
• Replace base64-like payloadToSign examples with canonical compact JSON Turnkey activity payloads.
• Fix the export curl continuation in the touched wallet export snippet.

Test Plan

• git diff --check main...HEAD
• Targeted rg scan for stale base64 payloads, bare UUID Request-Id headers, and old signed-retry payload shapes.

Greptile Summary

This PR updates the signed-retry pattern examples across three documentation snippets to align with the real Turnkey payload format and current Request:<uuid> request ID shape.

• Replaces opaque base64 payloadToSign placeholders with canonical compact JSON Turnkey activity payloads (ACTIVITY_TYPE_UPDATE_USER_EMAIL, ACTIVITY_TYPE_DELETE_AUTHENTICATORS, ACTIVITY_TYPE_DELETE_API_KEYS, ACTIVITY_TYPE_EXPORT_WALLET) and updates all requestId values and Request-Id headers to the Request:<uuid> format.
• Fixes a broken multi-line curl command in exporting-wallet.mdx where a missing backslash continuation caused -H \"Content-Type: application/json\" to be interpreted as a separate shell command rather than part of the curl invocation.

Confidence Score: 5/5

Safe to merge — all changes are documentation-only updates to example payloads and header values with no runtime code affected.

The changes correctly and consistently update three documentation snippets: the broken curl continuation in the export flow is fixed, the requestId format is aligned to Request:<uuid> in every affected header and JSON block, and the opaque base64 placeholders are replaced with realistic Turnkey activity JSON that matches the described activity types. No logic, schema, or API contract changes are involved.

No files require special attention.

Important Files Changed

Filename	Overview
mintlify/snippets/global-accounts/authentication.mdx	Updated requestId format and payloadToSign examples for the EMAIL_OTP and PASSKEY signed-retry flows; all curl headers and JSON payloads are internally consistent.
mintlify/snippets/global-accounts/exporting-wallet.mdx	Fixed the missing \ continuation after -u on the first export curl call, and updated payloadToSign/requestId to match the new canonical format.
mintlify/snippets/global-accounts/managing-sessions.mdx	Updated session-revocation example with ACTIVITY_TYPE_DELETE_API_KEYS payload and Request:<uuid> format; DELETE curl remains correctly without a body continuation.
